apt-get install percona-xtrabackup should require qpress

[Vadim Tkachenko]

I installed xtrabackup as
apt-get install percona-xtrabackup
and it was successful,
but then innobackupex --decompress failed because qpress not found.

We should require qpress package in this case too

Making it a dependency was my original plan, but then a different approach was suggested by Ignacio in a devteam@ discussion:

"I'm having second thoughts on adding qpress as a dependency on our xtrabackup packages, though. I understand that many users install the percona-xtrabackup rpm or deb package directly via download + rpm/dpkg -i, without using our repos. Depending on qpress will have installation fail to all these users, and may ("will") force them to use our repository even if they don't want to. "

I guess it's easy to change, but should we?

We also have to package qpress for all distros, and do it properly as
we're getting XB included in them.

@#1,

Yes, that reasoning makes sense, particularly when PXB is used without percona repo, ie. with mysql and mariadb installed. But, there is another way around this - ie. to indicate the dependency. Currently, there is no dependency indicated except through docs. One way to do this is with 'Optional Dependencies' option. Both RPM and DEB should support it I think. (in their own ways). One of them even allows to install with opt. dependencies during installation.

Bug #1261542 is a duplicate of this one.
